Direct bore-well recharge

Got a dry bore-well? We can revive it. Excessive digging of new bore-wells and incessant use of existing ones has resulted in severe depletion of groundwater levels rendering many a bore-well dry. SRDS’s direct bore-well recharge technique combines common rainwater harvesting practices with innovative practices to replenish ground-tables and aquifers with naturally filtered rainwater. SRDS’s ingenious solution to this issue involves the excavation of a pit sized 10x10x10 feet (in most cases) around the tube-well’s casing pipe. Tiny slits are made into the casing pipe which is then wrapped with nylon-mesh. Cement rings are laid one upon another around the pipe thus creating a circular structure in the centre of the pit. The rest of the pit is packed with natural filtration material i.e. stones and sand. Adjoining this pit referred to as the primary percolation pit, a large pond is excavated. During the rains, rainwater from the plot is directed to this catchment pond via a series of trenches or piping. The water then enters the primary percolation pit and after undergoing filtration via the stones and the sand seeps in through the gaps between the cement rings. After a final round of filtration by the mesh, the water enters the casing pipes through the tiny slits thus going back underground to replenish the water tables and aquifers. The result…?

Increased water-output: Bore-wells recharged using our technique have an increased water-output. Completely dry bore-wells can be revived too.

Better water-quality: Sending back of naturally filtered rainwater into the groundwater tables results in a decrease in the proportion of impurities in the water. The bore-well’s water thus loses its hardness with time.

Cost-effective: The use of locally procured natural materials enables us to deliver the bore-well recharge service at an extremely low cost.

Permanent: Once recharged a bore-well never goes dry. Year after year, underground water-tables and aquifers are replenished thus keeping your bore-well up and running.

Customizable: It doesn’t matter if you’re a farmer with your bore-well on a farm-land or if your bore-well lies on the site of an industry / farm-house / educational institute or any other urban site. Our technique can be customised to meet your needs.

Eco-friendly: Apart from resolving your water-scarcity issue, our bore-well recharge technique also ensures the storage of naturally filtered rainwater in natural water-reservoirs i.e. aquifers and water-tables for use by future generations.
